Win32-versions of GNU tools, or tools with a similar open source licence. The ports are native ports, that is they rely only on libraries provided with any 32-bits MS-Windows operating system, such as MS-Windows 95 / 98 / 2000 / NT / XP
provides a simple interface for defining and accessing command line arguments. It was intially inspired by the user friendly CLAP libary.

While the library is not strictly compliant with the GNU or POSIX standards, it is close.
